1STQ008691A0000 ABB PSHS1904 Horizontal Shelf W400 mm System pro E power

Why Choose the ABB PSHS1904 Horizontal Shelf?

The ABB PSHS1904, manufacturer order code 1STQ008691A0000, is a dedicated horizontal shelf accessory for compatible ABB System pro E power low-voltage electrical switchboards. Identified by the manufacturer's designation HORIZONTAL SHELF W=400MM, this component is specified for a nominal switchboard width of 400 mm.

Part of the ABB System pro E power modular switchboard range, the PSHS1904 supports the mechanical organisation of compatible electrical distribution assemblies. Horizontal shelves can form part of a structured internal layout, providing a defined horizontal component within the switchboard construction when installed in accordance with the manufacturer's approved arrangement.

The ABB PSHS1904 horizontal shelf is particularly relevant to professional switchboard manufacturers, electrical contractors and industrial maintenance teams requiring a manufacturer-specific accessory for a 400 mm nominal width configuration. Its exact installation position, mounting requirements and compatibility with adjacent structural components should be verified using the applicable ABB assembly documentation.

Key Advantages

• Dedicated horizontal shelf accessory for ABB System pro E power switchboards.
• Specified for a nominal switchboard width of 400 mm.
• Supports organised internal layouts in compatible low-voltage electrical assemblies.
• Provides a manufacturer-specific component for modular switchboard construction.
• Helps panel builders select the appropriate shelf for the intended structural arrangement.
• Supports consistent switchboard assembly using compatible ABB components.
• Offers a clearly identifiable replacement and procurement reference.
• Can be included in electrical project specifications and switchboard bills of materials.
• Relevant to industrial and commercial power distribution installations.
• Supports professional installation planning when used with verified ABB mounting instructions.

400 mm Horizontal Shelf for ABB System pro E power Switchboards

Low-voltage electrical switchboards incorporate a range of structural and internal accessories to accommodate electrical equipment and organise the assembly. These may include mounting supports, shelves, partitions, covers and framework components. The ABB PSHS1904 is specifically identified as a horizontal shelf within the System pro E power range.

The manufacturer's designation HORIZONTAL SHELF W=400MM establishes the shelf's horizontal configuration and its specified 400 mm width application. This dimension is important when selecting components for a particular switchboard arrangement. However, the designation does not independently establish the exact external shelf measurements, depth or thickness, which should be checked against the applicable ABB technical drawing.

Correct selection also depends on the surrounding switchboard structure. A horizontal shelf intended for one enclosure width or internal arrangement should not automatically be considered interchangeable with shelves designed for other configurations. Panel builders should confirm the mounting points, required fixings, adjacent components and any applicable installation clearances before assembly.

The PSHS1904 is a mechanical accessory rather than an electrical protective device. The supplied specification does not establish a permissible equipment load, a particular form of internal separation or an independent ingress protection rating. Where the shelf contributes to an equipment-supporting or compartmentalisation arrangement, its suitability must be assessed using ABB's verified system documentation and the requirements of the complete switchboard.

Typical Applications

• ABB System pro E power low-voltage electrical switchboards.
• Horizontal shelf installations in nominal 400 mm wide switchboard configurations.
• Internal mechanical organisation of compatible distribution assemblies.
• Professional electrical panel manufacturing and assembly.
• Industrial electrical power distribution installations.
• Commercial building switchboard projects.
• Replacement of matching ABB horizontal shelf components.
• Switchboard procurement and assembly projects requiring manufacturer-specific accessories.
